The devastating fire that destroyed much of the west wing of Charles Rennie Mackintosh’s masterpiece, the Glasgow School of Art, has been well-reported. Well done to the fire services and the staff of the School who had the difficult task of dealing with the fire and trying to minimise the impact on this historic building and on the contents, including the work of the students. Thank goodness that the School has recently opened its new building across Renfrew Street, so is able to continue to operate. In terms of heritage, the exterior looks as if it can be restored and the most devastating loss internally is that of the famous library, a masterpiece of its day, which everyone seems to agree should be recreated and, given that most of the drawings exist, this should be possible. What however of the rest of the interiors, especially those that were perhaps quite utiitarian? What would Mackintosh have done? Is this an opportunity for an imaginative architectural solution that restores the best of Mackintosh but in other spaces creates some new and innovative 21st century architecture to meet the College needs of the 21st century. This is the organisation that commissioned Steven Holl for its latest building. It is at least worth having a debate.
